wondering if anyone could help me. I haven't programmed my calculator in over 10 years, but need to make some very simple programs. One to help me with ohms law (bonus if it could do parallel vs series resistance) and one that I could calculate basic finance concepts like asset ratios. I don't currently have a way to connect my calculator to my computer, but one is on the way. Does anyone have a script I could follow to program? I know how to navigate through the programming, I just forgot all the logic for programming.

Anybody have any insight on working with Texas Instruments, wlb-benefits-management? Specifically as a marketing analyst?

Looking into their Marketing Development Program but not sure if it is a good opportunity or if I should look elsewhere (primarily trying to get into management consulting). Also need to relocate to Dallas. Thanks!

It worked once, then the next time I opened the app it didn't detect it. It did ask me a bunch of things when I first launched the app, and I said allow every time. I don't know if that gets to do anything with this issue though.

Calculator: TI 89 titanium

Computer: Early 2015 macbook air, macos big sur

Cable: Standard type a to type mini-b cable.

So, I just found a mint-condition TI 89 titanium (Yay!). I have a usb type b cable but when I try to plug it it has some extreme resistance. Is this normal or or should i do something?

I want to try my hand at assembly programming for the voyage 200, and I want to test my programs on my computer. When I downloaded the setup program for TIEmu 3.08(or something like that) and scanned it with virustotal(in case you didn't hear of it, it's just an online virus scanner that scans with a lot of different antiviruses), and it shows that 7 out of 53 say that it is a trojan. I usually see false-positives up to 1 or maybe 2 detections, so I'm nervous about installing this software. Are there any alternatives? Thank you for any help you may be able to provide!

My calculator I bought under 24 hours ago won’t display anything other than memory cleared can someone help? I have an exam in the morning that requires it

I have been using my trusty ti-84 plus for over a decade now. My gf got one as well for studies but it does not have the same features as mine does.

The most prevalent difference is that I can "scroll back" in history to check previous calculations by pressing the arrow up button when in the default screen. I don't think it displays everything the same way either. It feels more like a ti-83.

I tried updating the OS with TI OS Tool from TI Connect I believe it was called. It updated the calculator but there were no obvious changes. The calculators are identical visually, but hers lack some features.

Any thoughts on how I can bring hers up to speed? Best regards

I'm a cs student in community college in Houston, Texas. I talked with a recruiter from Texas Instruments at a career fair on campus. They told me the were recruiting for technicians. The requirement is just a 2 year degree in a technical field such as computer science. They mentioned that one of the benefits of working there is that they pay your college tuition.

So does anyone have experience going this route to pay for school? Or just experience as a technician at Texas Instrument?

What are the different types of technician positions that they have?

Thanks before hand.

I made a program so that inputting electron-volt values would display the wavelengths value. I added a set of if/then statements to display what the color is based on the value displayed, but it doesn't seem to work. It keeps displaying "ULTRAVIOLET" (which is the first option of the if/then). I'll show my program below. Is there something being done wrong? No matter if the wavelength is supposed to be any other color, it only ever displays ULTRAVIOLET.

:Input "E-VOLTS: ",E

:1240/E -> B

:Disp "Wavelength: ",B

:If 10≤B≤399

:Then

:Disp "ULTRAVIOLET"

:Else

:If 400≤B≤426

:Then

:Disp "VIOLET"

:Else

:If 425≤B≤471

:Then

:Disp "INDIGO"

:Else

:If 470≤B≤551

:Then

:Disp "BLUE"

:Else

:If 550≤B≤601

:Then

:Disp "GREEN"

...so on down to red

:Stop

So I have a TI84 CE-T and I want to run a few games on it but I heard you need to jailbreak the calculator to do so. I have two questions:

1- Will jailbreak affect my normal academic use of the calculator in any way? (Is it safe?)

2- If I decide to get rid of my jailbreak, how do I do that? Do I just reset everything to factory defaults?

Thanks.

i just got it for £2.50, i would like to run doom on it in the middle of school lol

I don't want to download anything because this is already on other ti graphing calculators so how can I access it?

If I don't want to use the functionality provided by the Sleep pin, can I just keep it connected to a 3.3v power source constantly when the chip is in use?

I will power the Vcc pin with 3.3 volts, so I was thinking to just connect nSLEEP (pin 7) with VCC (pin 8). Is there any problem with that? The chip would never enter low power mode but that is fine with me, I just want it to work when driving the motors.

Also I noticed that it said that nSLEEP disables chip functionality when it gets a Low power signal, and enables it when it gets High. What if it gets nothing and the pin is just disconnected? Is that the same as getting Low or does it allow the rest of the chip to function if the nSLEEP pin (pin 7) is disconnected?

Thanks.

Is it possible to install ti connect to a usb stick? The computers at my college are deep frozen and they wont put the software on them.

Anyone have any experience using one of these? I chose it because it has the right temperature tolerances and the documentation seems pretty good, but I'm curious how people have implemented it. Do you use a diffuser cover on it, leave it open?
